1883.] NATURAL SCIENCES OF PHILADELPHIA. 333 



It is very desirable that the Herbarium of the Academy should 



be in such condition as will make it most accessible and useful to 



botanists who may visit it during the meeting in this city next year 



of the American Association for the Advancement of Science and 



of the British Association ; and though it will be impossible to do 



all that should be done in the brief intervening period, it is hoped 



that much may be accomplished towards this end, and that good 



progress may be made in the mounting of at least the North 



American plants.

REPORT OF THE MINERALOGICAL AND GEO- 

 LOGICAL SECTION. 



Meetings of the Section have been held regularly during the 

 year, the attendance averaging from eight to ten. The discus- 

 sions have been more upon geological questions than upon 

 mineralogical, owing to the interest excited by the Geological 

 Survey of the State. The most important event to the Academy 

 in connection with mineralogy has been the accession of the Vaux 

 collection, and its arrangement b}^ Mr. Jacob Binder, whose ser- 

 vices in that matter have been of exceeding value. 



The officers of the Section are : — 



Director^ .... Theodore D. Rand. 



Vice-Director^ . . . W. W. Jefferis, Esq. 



Recorder and Secretary^ . Dr. A. E. Foote. 



Conservator, .... Prof. H. Carvill Lewis. 



Treasurer, .... John Ford. 



Respectfully submitted, 



Theodore D. Rand, 



Director.
